对30例目击下心跳骤停患者复苏后早期动脉血气变化进行分析,探讨复苏期间体内酸碱状态的变化规律、影响因素及预后意义。结果显示,复苏期间酸碱失衡的发生与 CPR 持续时间、碱性溶液应用及通气状况等多种因素有关;出现重症酸中毒提示预后不良。充分的通气供氧是复苏期间防治酸中毒的基本措施,过度通气可部分代偿代酸,CPR 时间在10～15分钟以内者无须补碱,超过这一时间则有必要在动脉血气分析结果指导下适量补碱。但动脉血正常血气的预后意义尚须探讨。
The change of arterial blood gas in the early recovery after cardiac arrest in 30 patients undergoing cardiac arrest was analyzed to explore the change law, influencing factors and prognostic significance of acid-base status during the resuscitation. The results showed that the occurrence of acid-base imbalance during resuscitation and CPR duration, the application of basic solution and ventilation and other factors; severe acidosis prompted a poor prognosis. Adequate ventilatory ventilation during resuscitation is the basic measure to prevent and control acidosis. Hyperventilation can partially replace the acid, CPR time within 10 to 15 minutes without alkali, beyond this time it is necessary to guide the results of arterial blood gas analysis Under the right amount of alkali. However, the prognostic significance of arterial blood normal blood still needs to be explored.
